The hand warmers work awesome while the battery stays charged. The issue is that the battery doesn’t last anywhere close to what is advertised. Both warmers died running on the lowest setting after about 4 hours. This is not ideal for using in the 15° F weather I bought them for. Read more
I purchased for early morning golf t-times in 35f they worked well for 30 min after that very poor performance kept shutting off turn back on they would warm up some. I don’t usually give bad reviews but these just didn’t work well for my needs. Read more
I charged both of these warmers equally, to a full charge. I turned them both on to the lowest setting. One barely got over 95 degrees, while the other was nearing 120 degrees on the lowest setting according to my digital meat thermometer. The temperature fluctuated drastically. At times the one would burn my hand and I couldn't leave it on the warmer for more than a couple seconds, while the other was barely warm. I returned them due to the temperature not being regulated correctly. Read more
It seems like these wont last a 8 hr day but it states 20 hrs. I had it on level 1 also. I think one of mine is damaged. I only used this two times so far. Read more
Differently not worth it. It feels like your holding warm 9v batteries. Very small and they don't heat up all around. My hands heated the bottom, the bottom was ice cold Read more
It never got a complete charge with the battery. The heat was minimal. I had to give it a star to do a review of it. (Tried not to give any stars which would be my choice.) Read more
When I first used them they were great, stuck to level 1 and they did what they should. However, today I was out hunting in sub freezing temps and turned them up to level 2. At this level they got extremely hot to the point where I had to turn them down, but afterwards I looked at my hand and had visible burn marks from them. Which is scary considering I've met my 7 year old daughter use them before too. For a fancy regulated chip set, these should never get that hot. Read more
Don’t buy if you want hand warmers that last. These don’t hold charge! States 20 hours of heat, and I get between 3 hrs and 50 minutes and 7 hours out of them on the lowest setting. Save your money. I’ve used and charged them several times trying to get more life out of them and they just don’t last! Read more
